T (Lu "whom, it may concern..-

Be it known that I, PHILIP L. KOSOIALOW- sin, of the city of St. Louis and State ofMissouri have invented a certain new and useful Improvement in Carriage and 'Wagon Jacks, of which the following is a full, clear, and ex act description, reference being had to them:- companying drawings, forming part of this specification.

Figure 1 is a side view of the jack with a wheel-hub shown in section. Fig. 2 is a perspective View of the jaclz. 3 is a vertical section with the lifting-bar in its lower position. Fig. 4 isa horizontal section at 4. 4, Fig. 1.

A is a hollow stand having a base. B, and lugs O, to which the treadle-lever D is fulcrunied. The treadle has a cog-sector d, at the end, which engages a cog-rack, 6, upon the edge of the lifting-bar E. Thelil'ting-bar works in the stand A. The head E has preferably a returnbend, as shown. so that the nose 6- shall not project far beyond the base,

and the weight of the wheel F, when drawn off the spindle G, may be over the base. The nose has a rounded or curved form, as shown in Fig. 2, so that it. fits the shank g of the spin die-screw g, and thus the end of the axle is sustained upon the nose while the hub of the wheel is drawn out on the horn or bow (See Fig. 1.) The lifting-bar E is sustained when in its elevated position by the treadle lever, the sector cl engaging with rack e, the t-readle itself being held in the position shown in Figs. 2 and 3 by a hinged dog or pawl, H,

which engages teeth (1 upon the treadle.

I is a pin, which may be inserted in the holes i of the stand and bar to hold the bar in the position shown in Fig. 3. When the pin I is inserted in holes i, thehead Emay be used as a handle to carry thejack.

The operation is as follows: The nut is removed from the spindle-screwy and the washor from the shank y (if thereis a washer used) while the wheel is upon the ground. The jack is then placed in position outside thewheel and the nose 6 inserted beneath the screw and shank. is in the position shown in Fig. 3 the liftingbar may be moved freelyin the stand. \Vhen the nose has been inserted beneath the screwshanl;,the outer end of the treadle is depressed, and the wheel thus lifted from the ground. The wheel is then pulled outward until the hub leaves the spindle, and is carried upon the horn e. The bar B may be sustained by the pressure of the foot or by means of the dog H.

When it is desired to removethe wheel away from the vehicle, the jack may be used in the manner of an ordinary jack, being put beneath the axle inside the wheel. For-this use of the jack I cast upon the head knobs e" 0 to prevent the axle slipping on the head.

I claim- 1. A jack comprising astand having an arm or horn adapted to sustain the end of the axle on the stand and to receive the wheel as it is removed from the spindle.

2. The combination, in the lifting-bar of a jack, of a curved nose adapted to engage the spindle end before the removal of the wheel from the spindle, and a horn, of which the nose forms the extremity, adapted to enter the bore of the hub and support the wheel.

3. The combination of lifting-bar having a horn, c, with nose 6 and cog-rack e, and a treadlelever, D, with cog-sector d, engaging the rack e, substantially as set forth.

4.. The combination in the lifting-bar E, of the head having a return-bend with horn e and nose e, substantially as and for the purpose set forth.
